| titleOfInvention | WATER TREATMENT PROCESS |
| abstract | Acidic water containing toxic aluminum concentrations (0.1 ppm) is treated by dissolving silicate in an amount containing a solution having a concentration of at least 40, preferably at least 100 micromoles of silicon per liter of water and a silicon: aluminum ratio ( based on the metals) of at least 6: 1 and preferably 10: 1 in water to form a nontoxic complex with aluminum, as well as by dissolving alkali or alkali metal ions to increase the p H value of the water. The preferred treatment agent is a hydraulic calcium silicate in the form of cement clinker, optionally enriched with silicon by a soluble silicate. |
